Great for lubricating stabilizers. Not recommended for switches.
From the manufacturer:
XHT-BDZ is the highest viscosity grease in the XHT-BD Series. Krytox XHT-BD greases are designed for use where the temperatures are in the 288 °C (500 °F) range and higher, where there is a danger of melting the standard PTFE thickener. This grease uses a special non-melting high temperature thickener. The base oil is an extremely viscous oil that provides good viscosity and lower evaporation at high temperatures. Krytox XHT-BD greases are for use in low speed bearings or in pillow housings and will shear at high speeds, causing loss of oil in sealed bearings. The oil in the grease can begin to slowly evaporate at temperatures above 330 °C (626 °F), and this will occur at an increasing rate as temperatures increase. Re-lubrication could be required at these temperatures to achieve optimum life.
Masterfully crafted in Toronto, this lube is a remix of Hugo's Thick Lube V1. We've been able to get this product industrially made and tested to have the same SDS properties as Krytox 205g0. Comprised of the same base PTFE and PFPE but at a much lower cost. Direction: Whip gently before use. Apply to affected areas carefully using a fine brush. Remove excess as required. Keep away from pets and dust.
